Possible System configuration

Source 1: Benchmark DAC HDR

Source 2: Linn Majik LP 12

Phonostage: Linn Uphorik

Amplifier: McIntosh 275

Speakers: Sonus Faber Cremona Auditor M

Question 1: do I need a preamplifier in the above configuration or can I plug the Linn Uphorik directly into the McIntosh 275

Question 2: can I plug in the benchmark and Linn Majik into the Linn Uphorik phono stage XLR cables and then run them directly into McIntosh 275 selecting the source when i need.

Question 3: I am looking for a musical non-fatigue sound. I listen to mostly Opera and Jazz, will this system deliver?

Thanks and appreciate experienced audiophile advice!
